Image of Board

The ESP32-C6-DevKitC-1-N4 is an entry-level development board equipped with ESP32-C6-WROOM-1, a general-purpose Wi-Fi + Bluetooth LE RISC-V MCU module that integrates complete Wi-Fi and Bluetooth LE functions. This board integrates complete Wi-Fi, Bluetooth LE, Zigbee, and Thread functions.

This version is equipped with the ESP32-C6-WROOM-1 with 4MB Flash.

Most of the I/O pins on the module are broken out to the pin headers on both sides of this board for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-C6-DevKitC-1-N8 on a breadboard. We particularly like that there’s a debug UART/USB port and a separate native USB port, so you can upload/debug/USB all at once.

At the core of the modules is an ESP32-C6, a RISC-V 32-bit single-core CPU that operates at up to 160 MHz. You can power off the CPU and make use of the low-power co-processor to constantly monitor the peripherals for changes or crossing of thresholds. ESP32-C6 integrates a rich set of peripherals including SPI, LCD, Camera interface, UART, I2C, I2S, remote control, pulse counter, LED PWM, USB Serial/JTAG controller, MCPWM, SDIO host, GDMA, TWAI® controller (compatible with ISO 11898-1), ADC, touch sensor, temperature sensor, timers, and watchdogs, as well as up to 45 GPIOs. It also includes a full-speed USB 1.1 On-The-Go (OTG) interface to enable USB communication

There are three mutually exclusive ways to provide power to the board:

  • USB Type-C to UART Port, default power supply
  • 5V and GND pin headers
  • 3V3 and GND pin headers

It is recommended to use the first option: USB Type-C to UART Port.

Components:

  • ESP32-C6-WROOM-1: ESP32-C6-WROOM-1 is a general-purpose module supporting Wi-Fi 6, Bluetooth 5, and IEEE 802.15.4 (Zigbee 3.0 and Thread). This module is built around the ESP32-C6 chip, and comes with a PCB antenna and 4 MB SPI flash.
  • 5V to 3.3V LDO: Power regulator that converts a 5V supply into a 3.3V output.
  • 3.3V Power On LED: Turns on when the USB power is connected to the board.
  • Pin Headers: All available GPIO pins (except for the SPI bus for flash) are broken out to the pin headers on the board for easy interfacing and programming. For details, please see Header Block.
  • USB-to-UART Port: Single USB-to-UART bridge chip provides transfer rates up to 3 Mbps.
  • ESP32-C6 USB Type-C Port: The USB Type-C port on the ESP32-C6 chip is compliant with USB 2.0 full speed. It is capable of up to 12 Mbps transfer speed (Note that this port does not support the faster 480 Mbps high-speed transfer mode).
  • Boot Button: Download button. Holding down Boot and then pressing Reset initiates Firmware Download mode for downloading firmware through the serial port.
  • Reset Button: Press this button to restart the system.
  • USB-to-UART Bridge: Used for power supply to the board, as well as the communication with the ESP32-C6 chip via the on-board USB-to-UART bridge.
  • RGB LED: Addressable RGB LED, driven by GPIO8.
  • J5: Used for current measurement. See details in Section Current Measurement.

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. These releases are even newer than the development release listed above. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Previous Versions of CircuitPython

All previous releases of CircuitPython are available for download from Amazon S3 through the button below. For very old releases, look in the OLD/ folder for each board. Release notes for each release are available at GitHub button below.

Older releases are useful for testing if you something appears to be broken in a newer release but used to work, or if you have older code that depends on features only available in an older release. Otherwise we recommend using the latest stable release.
